Assembly Language Tutorial (x86) For more detailed information about the architecture and about processor instructions, you will need access to a 486 (or 386+) microprocessor manual. The one I like is entitled The 80386 book, by Ross P. Nelson. (This book is copyright 1988 by Microsoft Press, ISBN 1-55615-138-1.) Intel processor manuals may also be found at http://www.x86.org/intel.doc/586manuals.htm. The GNU Assembler, gas, uses a different syntax from what you will likely find in any x86

Instruction Sets: Characteristics and Functions The essential elements of a computer instruction are the opcode, which specifies the operation to be performed; the source and destination operand references, which specify the input and output locations and for the operation; and a next instruction reference, which is usually implicit. (understood) Opcode specify operation in one of the following general categories: arithmetic and logic operations; movement of data between two registers, register

addressing mode of the instructions. The addressing mode specifies a rule for interpreting or modifying the address field of the instruction before the operand is actually referenced. Computers use addressing mode techniques for the purpose of accommodating one or both of the following provisions: 1 Addressing Modes Computers use addressing mode techniques for the purpose of accommodating one or both of the following provisions: 1. 2. to give programming versatility to the user by providing

Chapter 3: Jump, Loop, and Call Instructions 3:1: Loop and Jump Instructions 1. In the 8051, looping action with the instruction “DJNZ Rx, rel address” is limited to decrement iterations. 2. If a conditional jump is not taken, what is the next instruction to be executed? Unconditional jump 3. In calculating the target address for a jump, a displacement is added to the contents of register program counter. 4. The mnemonic SJMP stands for short jump and it is a 2-byte instruction.
